Rudder Leading Edge

Forming the leading edge of the rudder consists of bending the skins in a semi-circle fashion, getting them to meet in the middle, then riveting them together. You must do this without folding the skin, and without bending the skin right at the forward spar. The curve must be uniform. And, the bends must go far enough so that, later, you aren’t putting too much spring-tension load on the rivets that will hold them together in the middle.

I found it very difficult to get the skins curved as much as I wanted – there was definitely some spring tension in them when I went to riveting. But, I also understood that this is to be expected to some degree. It took far longer, and it took far more muscle and working it through, to get decent results. Here’s how I did it:
